BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to networked computing systems. In particular, the present invention is directed to networked computing system adapted to be used in industrial applications, such as shops, department stores, kitchens, and the like.
2. Description of the Prior Art
In many industrial automation systems, common requirements include:
-
- 1. high reliability;
- 2. functionality;
- 3. low cost;
- 4. endurance in harsh environments;
- 5. conformity to industry standards in interface protocol and network topology; and
- 6. small physical size and rugged housing.
For example, one application with the above demanding specifications is a Kitchen Display System (KDS), which is used in restaurants. KDS offers many intelligent features and functionality that improve the productivity of restaurant operations. KDS must be reliable because during busy rush hours, an equipment failure in such systems is not acceptable, no matter how infrequently such failures may occur.
Typical industrial networked computing systems include microcontroller-based workstations networked using RS-485 or RS-232 interface standards with an additional control unit. More customized systems incorporate microprocessor-based workstations that are networked using Ethernet interface standards. However, neither of these approaches when taken alone, is completely successful in meeting the needs of the industry.
For example, in some applications, the performance and cost of microprocessor-based workstations may be unnecessary, and yet an Ethernet topology would be desirable to interface with existing hardware. In other network settings, a particular industrial application might require the advanced performance and capabilities of a microprocessor-based workstation at only some of its sites.
SUMMARY OF THE INVENTIONA Point-of-Sale networked computing system is provided in accordance with the present invention, which includes a workstation including a first Personal Computer (PC)-based controller, a workstation including a second industrial PC-based controller with different performance characteristics than the first industrial controller, and an Ethernet network operatively coupling the workstations. The Ethernet network may include a home-run or star Ethernet topology, and at least one of the industrial controllers may be adapted to be TCP/IP addressable. The computing system may be adapted for use in a restaurant, kitchen, shop, or store. The computing system may also include a bump bar keyboard or keypad and a monitor operatively coupled to at least one of the industrial controllers.
A Point-of-Sale networked computing system is further provided in accordance with the present invention, which includes at least two workstations, each of which includes an industrial non-PC-based controller, and an Ethernet network operatively coupling the workstations.
A Point-of-Sale networked computing system is yet further provided in accordance with the present invention, which includes a workstation including an industrial PC-based controller, a workstation including an industrial non-PC-based controller, and an Ethernet network operatively coupling the workstations.
These and other objects, features, and advantages of this invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Kitchen Display Systems (KDS) can be categorized into two groups: industrial Personal Computer (PC)-based workstations and industrial non-PC-based workstations. In the industrial PC-based workstation group, a workstation 10 is shown in
The disadvantages of this system include:
-
- 1. Expensive—the general purpose PC 12 provides far more performance than is required by most applications, and can perform many advanced tasks that are not required in KDS applications.
- 2. Compromised reliability—the PC is a general-purpose piece of complicated equipment, which typically provides numerous sources of failure.
- 3. Environmental concerns—almost all PCs have a built-in fan for cooling, which are prone to getting fouled in a greasy kitchen environment.
- 4. Size—standard PCs are generally too large to fit into the limited space of a kitchen.
In the industrial non-PC workstation group, a typical workstation 22 is shown in
The disadvantages of this system include:
-
- 1. an unfamiliar network topology; that is, installers and service technicians are more familiar with Ethernet topology;
- 2. a lack of multimedia capability, such as an inability to display high-resolution video; and
- 3. a master control unit 28 that requires substantial additional hardware overhead, that is, the master control unit 28, which is an extra piece of equipment that is normally not required in industrial PC-based systems.
Additional information concerning industrial non-PC workstation systems and related matters is provided in application Ser. Nos. 10/714,592, filed Nov. 14, 2003 entitled “Point-of-Sale System and Distributed Computer Network for Same”; 11/244,313, filed Oct. 5, 2005 entitled “Rugged Industrial Computer Module”; and 11/431,378, filed May 10, 2006 entitled “Rugged Computer Module”, which are incorporated herein by reference.
A networked computing system formed in accordance with the present invention is not limited to exclusive use as a Kitchen Display System (KDS), but may be used in any industrial application, such as but not limited to department stores, kitchens, shops, and other Point-of-Sale (POS) applications, and offers most of the advantages while overcoming the disadvantages in the aforementioned industrial PC-based and industrial non-PC-based systems. As shown in
A typical workstation includes a non-PC-based I/O unit or controller 32, a bump bar keyboard or keypad 34, a VGA monitor 36, and possibly a printer (not shown). Each I/O unit 32, which is labeled “LS6000” in
Despite the fast return on an initial investment, the equipment purchase price for industrial applications, such as restaurants, must be competitively low. Because a Kitchen Display System (KDS) typically operates in a hot and greasy kitchen environment, the equipment must be capable of withstanding a high operating temperature. Further, fanless operation is useful to avoid clogging by grease. To install and maintain such equipment, technicians should be able to understand operation of the equipment with a minimum of training. In most restaurant facilities, space is a very limited resource. Therefore, the physical size of the equipment and its ruggedness are desirable features.
Thus, in modern restaurant kitchen display systems (KDS), customers typically require many demanding features. These features include:
1. high reliability;
2. low cost;
3. the ability to operate in hot, greasy, and high humidity environments;
4. small physical size;
5. flexible mounting options;
6. fanless operation;
7. built-in self diagnostics;
8. Ethernet topology with IP addressable workstations;
9. built-in build cards; and
10. the ability to run high-resolution video for training purposes.
Features 1 through 7 are satisfied by the controller 24 in the industrial non-PC-based system shown in
The workstations 12, 32 preferably also include firmware build cards, which can be stored in an internal CompactFlash® or any mass storage device, but preferably comprise a solid state memory device. Such a mass storage device is preferably removable from the workstations 12, 32 and capable of being reprogrammable, for example, by downloading information through the Ethernet and/or RS-232 interfaces.
CompactFlash® (CF) cards are small, removable mass storage devices, which are well suited to the present invention, are well known in the art, weigh about a half ounce or less, and are typically the size of a matchbook. CompactFlash® can provide complete PCMCIA-ATA functionality and compatibility.
The build cards preferably store recipes, videos, and/or programs tailored to each user's needs. For example, the build cards could enable an employee in a restaurant to learn how to prepare a particular food product without requiring personal training by more experienced employees. The workstations 12, 32 are preferably able to store a plurality of build cards or so-called “decks” of build cards.
Controllers 24, 32 preferably contain simple circuitry, which results in improved reliability and lowered cost. The hybrid system 30 shown in
In another embodiment of the present invention, industrial PC-based controllers 11, 12 present in the system and shown in
The Ethernet networks used in the present invention may incorporate so-called “home run” or “star” Ethernet topology, which is shown in
Although illustrative embodiments of the present invention have been described herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the invention.
